Lawrence's publicist verified that the photos are her, telling Buzzfeed: "This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence."

"These so called nudes of me are FAKE people. Let me nip this in the bud right now. *pun intended*," Justice tweeted Sunday.

But others are admitting they're real. Actress Mary Winstead tweeted: "To those of you looking at photos I took with my husband years ago in the privacy of our home, hope you feel great about yourselves."
